Phylogenetic analysis of selected SpaA1 genes.
A. Bacterial and phage genomes sorted by the number of ORFs matching the SpaA1/MZTP02 region (based on the up to 200 best hits in NR database). On the left, the actual number of hits is indicated. Color code: three bacterial genomes with the 17-15 ORFs matching the SpaA1/MZTP02 region:purple; three bacterial genomes with the 13-12 matching ORFs: light blue; the phage with the largest number of hits matching the SpaA1/MZTP02 region:orange. B, C, D. Unrooted maximum likelihood trees for three ORFs the SpaA1/MZTP02 region. Each terminal tree node is labelled with GenBank Identifier (GI) number and full systematic name of an organism. Color code is the same as in the . The SpaA1 phage sequences are shown in red. Bootstrap support (percentage) are indicated for selected internal branches.
